UNITED STATES PATENT OFFICE- MAHLQN E. LAYNE, OF LOS ANGELES, CALIFORNIA.

PACKER.

Application led November 23, 1916, Serial No. 132,970. Renewed November 3, 1919. Serial No. 335,508.

To all whom t may concern:

Be it known that-I, MAHLoN E.. LAYNF., a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvemenets in Packers, of which the following is a specification. This invention relates primarily to packing to be used to close the opening between pipes of different sizes, set one within the other. A particular use tov which the form of packing to be described can be put, and

' the one described herewith, is in well pipings or casings where one or more different sized tubes may be used in driving the well before reaching the bottom. ln applying the packer in this connection, I provide a special form of setting tool which will also be described as it forms part of the combination of my invention.

'lhe special objects of this invention are to provide a packing for a joint as described which can easily be inserted in the well and as readily-set after insertion; to provide a tool of special and novel design for accomplishing this purpose, and, at the same time by means of the same toolto set a length of screening or piping below-the joint packed,

the operation being carried on without the necessity of havlng to remove the pipe or rod connecting the tool with the surface of the ground between operations. These, together with such other objects as may hereinafter appear or are incident to my invention, l obtain by means of the construction illustrated in preferred form in the accompanying drawings, wherein Figure 1 isa side elevation, partly in section, illustrating mycombined packer and setting tool; Fig. 2 is a side elevation also partly in section, on an enlarged scale illustrating a detail of the setting tool; Fig. 3 is a section taken on the line 3 3 of Fig. 2; and Fig. 4 is an enlarged view of a section of the packer illustrating a detail to be hereinafter described.

` Referring to Fig. 1 ofthe drawings, the

main body of the packeris indicated by the numeral 7 which is threaded at the bottom,

as indicated at 8, for attachment to the screening member or pipe which is to be set at the same time with the packer. A short distance' above the threaded portion8 there is attached a band orcolla'r 9 upon which rests the canvas or other packing material 10. The lower portion of the main body 7 of the packer vabove the band 9 is turned smooth as shown at 11, above which are sawtooth projections 12 with the points project-ing down andl extending to within a short distance of the top of the body 7. At

the top of the body 7 and on the inside thereof is a left-hand thread 18, for a purpose which will be hereinafter explained. Around the outside of the main body 7 of the packer is placed a sleeve 14 swaged as at 15, with slots 16 cut therein and extending across said swaged portion. yOn the inside of thev Specification of Letters Patent.

portion 15 to allow the teeth to ride over oneA another in the downward movement of the sleeve 14. Then the sleeve 14 is pushed down, as hereinafter described, it will be seen that the packing L10 will be compressed longitudinally and expanded laterally to fill the space between the body 7 of the Apacker and the pipe which surrounds it.

Into ,the left-hand threaded portion of the body 7 is screwed the setting tool 18, which must also be provided with a left-hand thread to correspond with the thread 13.

To the top of this tool 'is threaded, with a right-hand thread, a coupling 19 which connectswith the pipe 20 used to set the packer and screen. This tool 18 is provided with a recess 21 in which are the dogs 22 provided with shoulders 23 at the top and 24 at the bottom, and adapted to be pushed outwardly at the bottom by means of the spring 25. The shoulders 24 strike against the inside of the recess 26 turned i-n the tool 18 when it l is unscrewed from the bodyI 7 and raised to the top of the sleeve 14, and the shoulders 23 at the top of the dogs are adapted to be engaged by the end of the coupling 19 when the latter is screwed down over the top portion of the tool 18. It will be understood of course, that the dogs 22 are merely pocketed in the recess formed in the tool 18, there being no non-rotative connection between the two. This permits the unscrewing of the tool 18 from the body 7 without disturbing or turning the lpacker as a whole.

The setting of the packer is accor'nplished` dogs 22 are thrown out by the spring 25,'

so that the shoulders 27 thereon project over the top of the sleeve 14 and engage therewith upon downward movement of the tool. Pressure is by this. means brought to bear upon the sleeve 14 which is forced down against the packing l() causing it to expand,

` the saw-tooth projections riding over one another during 'the operation. The center` of the tool is hollow as shown in Fig. 3, which permits ofthe wash tube 28 remaining in position while the packer is being set so that the screen or pipe below may be washed out after the operation is completed. It will be seen that my packer is simple in construeu tion and is easily and readily inserted and set, wthout disturbing in any Way, the parts of the packer or parts of the well mechanism.

I claim:

1. A packer for pipes comprising in combination a main body portion, a sleeve movable thereon, packing adapted to be compressed by movement of the sleeve, and mea-ns detachably connected to the main body portion whereby the packer is placed, said means being provided with dogs adapted to engage the sleeve to move the same upon disen agement with the main body portion.

2. he combination with a pipe adapted to receive an internal member, of an eX- pansible packing on the pipe, a sleeve movable longitudinally of said pipe and adapted to compress the packing, a hollow, setting tool supporting said pipe and through which the internal member may pass, and means on said tool adapted to engage said sleeve to move the same on release of said tool from the pipe.

3. A packer for pipes comprising in combination a main body portion, a sleeve slidable thereon having a reduced portion, the reduced portion and the main body portion being provided with interengaging means permitting movement of the sleeve in one direction only, packing adapted to be compressed by such movement, and slots in the sleeve at the reduced portion whereby movement of the sleeve is permitted.

4. A packer comprising in combination a main body portion, a sleeve slidable thereon, said body portion and said sleeve being provided with interengaging means permitting movement of the sleeve in onedirection only, packing adapted to be compressed by such movement, and slots in one of said members at the interengaging means whereby movement of the sleeve is permitted.

. A packer comprising in combination a main body porton, a sleeve slidable thereon,

Va reduced portion in the sleeve, interengaging serrated surfaces on the body portion and on the reduced portion of the sleeve, packing adapted to be compressed by movement of the sleeve, and slotsin the sleeve extending longitudinally thereof and across in one direction only, and packing adapted to be compressed lby such movement.

`Intestimony whereof I have hereunto signed my name.
